SR400

Yamaha’s classic big single has a genuine heritage and pureness of design that sets it apart from some other ‘retro’ models. There can be no doubt that the SR400 is the real thing, and with an authentic engine and chassis specification and original kick start mechanism, this charismatic twin-shock thumper is aimed at the many riders who are looking to rediscover the soul of motorcycling.

For many riders, the character, soul and image of a machine is far more important than its acceleration figures or potential lean angle. Fundamental qualities such as simplicity, ease of use and timeless design are more important to the SR400 owner. With its relaxed torque, light and agile chassis and sheer mechanical beauty, the SR400 is designed to appeal to riders looking for a motorcycle with a real heritage and character, and one which fully engages its owner.

In addition to its appealing character and easy performance, the SR400 also offers many possibilities for those riders who want to customise their machine, whether that involves adding a few bolt-on parts or going the whole way and creating a café racer, street scrambler or bobber.

At the soul of the SR400 is an air-cooled 4-stroke single cylinder SOHC 2-valve engine which is technically almost identical to the original design, with the major difference is the use of a new fuel injection system, which allows the bike to conform with current emissions regulations, and also makes the SR400 easier to start than the original model.

Our engineers wanted to ensure that the current model is true to its original character, and so the only way to start the new SR400 is to kick it. The SR400 runs an indicator on the right side of the cylinder head that shows when the piston is in the best position for starting, and a decompressor lever on the left side of the handlebar assists in starting the engine smoothly.

The SR400 is equipped with traditional upright front forks that give 150mm of wheel travel for a smooth ride and easy steering. At the rear end this classic big single is fitted with a proven twin shock system that offers 100mm of suspension movement.

Throughout its long history, the SR400’s fuel tank design has remained largely unchanged, with the only real ‘update’ over the years being different paint and graphics. The SR400 is equipped with the same familiar teardrop style fuel tank which is virtually identical to the original design, with the exception that the tank now offers a capacity of 12 litres.
